Wireless distribution system proxy caches

ABSTRACT

In embodiments of wireless distribution system proxy caches, a mobile network operator receives requests for television content from client devices, and communicates one of the requests to a content service that provides the television content for distribution to the client devices. Proxy caches are implemented to cache content data of the television content prior to the cached content data of the television content being wirelessly communicated to the client devices. The proxy caches are located at wireless distribution points of the mobile network operator, and the wireless distribution points communicate the cached content data of the television content from the proxy caches to the client devices.

BACKGROUND

Television content delivered over an Internet connection is an increasingly popular technology. In addition to short video clips and recorded movies, live television can be distributed via the Internet, and television programming can be streamed to a portable device, such as mobile phone or computer device. However, there remains bandwidth limitations to delivering live television and video content in real-time, particularly through telco and mobile operator networks that distribute television content to client devices via wireless communication.

Additionally, television content typically includes national and/or local advertisements. Local advertisements are generally distributed within a fixed geographic area, and are intended to reach potential consumers of goods and services within the designated, fixed geographic area. However, portable devices may receive television content and advertisements when moved through many different geographic advertising areas, while local advertising to a device remains constrained to a fixed geographic area.

SUMMARY

This summary is provided to introduce simplified concepts of wireless distribution system proxy caches. The simplified concepts are further described below in the Detailed Description. This summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.

In embodiments of wireless distribution system proxy caches, a mobile network operator receives requests for television content from client devices, and communicates one of the requests to a content service that provides the television content for distribution to the client devices. Proxy caches are implemented to cache content data of the television content prior to the cached content data of the television content being wirelessly communicated to the client devices. The proxy caches are located at wireless distribution points of the mobile network operator, and the wireless distribution points communicate the cached content data of the television content from the proxy caches to the client devices. A wireless distribution point emulates television multicast when the cached content data of the television content is communicated from a proxy cache to multiple client devices.

In embodiments of current device location advertisement distribution, a mobile network operator receives television content from a content service and can then communicate the television content to a client device via a wireless distribution point. A device location service determines that a current location of the client device is not within a geographic region associated with the client device. The geographic region that is associated with the client device may be based on a service contract with a user of the client device, or a billing zip code associated with the user of the client device.

The device location service updates the current location of the client device from location data that identifies the current location of the client device. The location data can include GPS location data or regional position data that correlates to the current location of the client device. The television content can then be updated for distribution to the client device along with advertisements that correspond to an advertising locale, which includes the current location of the client device. The device location service can also update the advertising locale for the client device as the client device is moved from one region to another.

DETAILED DESCRIPTION

In embodiments, a mobile network operator controls distribution of television content to various client devices via wireless distribution points. The mobile network operator receives requests for television content from client devices, and communicates one of the requests (as opposed to all of the requests) to a content service that provides the television content for distribution to the client devices. The content service can also provide advertisements along with the television content for distribution to the client devices. Proxy caches are located at aggregation points and at the wireless distribution points of the mobile network operator to cache content data of the television content, and/or to cache advertisements, prior to the cached content data being wirelessly communicated to the client devices. A wireless distribution point emulates television multicast when the cached content data of the television content is communicated from a proxy cache to multiple client devices.

The advertisements are generally directed to client devices that receive television content within a designated region or geographic area, and are intended to reach potential consumers of goods and services within the designated local region or geographic area, referred to herein as an advertising locale. However, if a client device is moved from one advertising locale to another, such as from one city to a city in another state, the local advertisements that correspond to a geographic region associated with the client device are likely not useful to a user of the device in the different advertising locale. A current location of a client device can be determined from location data that identifies the current location of the client device. The location data can include GPS location data or regional position data that correlates to the current location of the client device. The television content can then be updated for distribution to the client device along with targeted local advertisements that correspond to the current location and/or advertising locale of the client device.

While features and concepts of the described systems and methods for wireless distribution system proxy caches can be implemented in any number of different environments, systems, devices, and/or various configurations, embodiments of wireless distribution system proxy caches are described in the context of the following example devices, systems, and configurations.

FIG. 1 illustrates an example system 100 in which various embodiments of wireless distribution system proxy caches and current device location advertisement distribution can be implemented. The example system 100 includes a mobile network operator 102, such as a cell-phone provider and/or Internet service provider that facilitates mobile data and/or voice communications for any type of various client devices 104. The client devices include fixed and/or mobile devices that may be subscriber devices of the mobile network operator, and are configured to receive television content via wireless communication. The example system 100 also includes a content service 106 and/or other media content sources that communicate or otherwise provide media content and data to any number of the various client devices 104 via the mobile network operator 102 and a communication network 108.

The various client devices 104 may be implemented with any number and combination of differing components as further described with reference to the example device shown in FIG. 7. In this example, a client device 104 can be implemented as any one or combination of a television client device 110, a computer device 112, a gaming system 114, an appliance device, an electronic device, and/or as any other type of device that may be implemented to receive media content in any form of audio, video, and/or image data.

The various client devices 104 can also include wireless devices implemented to receive and/or communicate wireless data, such as any one or combination of a mobile phone 116 (e.g., cellular, VoIP, WiFi, etc.), a portable computer device 118, a media player device 120, and/or any other wireless device that can receive media content in any form of audio, video, and/or image data. A client system can include a respective client device and display device 122 that together render or playback any form of audio, video, and/or image media content and media assets. The display device can be implemented as any type of a television, high definition television (HDTV), LCD, or similar display system.

Any of the services and devices can communicate via the communication network 108, which can be implemented to include a wired and/or a wireless network that facilitates data communication. The communication network can also be implemented using any type of network topology and/or communication protocol, and can be represented or otherwise implemented as a combination of two or more networks, to include IP-based networks and/or the Internet. The communication network may also include mobile operator networks that are managed by the mobile network operator 102 and/or other mobile operators, such as a communication service provider, cell-phone provider, and/or Internet service provider.

The content service 106 can include media content servers to communicate, or otherwise distribute, media content and/or other data to the various client devices via the mobile network operator 102. In this example system 100, the content service includes storage media 124 to store or otherwise maintain various media content and data, such as media assets 126 (e.g., also referred to as television content and/or media content) and associated content metadata 128. The storage media can be implemented as any type of memory and/or suitable electronic data storage.

The media assets 126 can include any type of audio, video, and/or image data received from any type of media content source or data source. As described throughout, media assets are media content, and media assets can include music (e.g., digital music files of songs), television programming, movies, on-demand media assets, interactive games, network-based applications, and any other audio, video, and/or image data (e.g., to include program guide data, user interface data, advertising content, closed captions data, content metadata, search results and/or recommendations, etc.). A media asset may also include various display formats of the media asset, such as a high-definition display format and lower quality display formats.

The content metadata 128 can include any type of identifying criteria, descriptive information, and/or attributes associated with the media assets 126 that describes and/or categorizes the media assets. For example, metadata can include a media asset identifier, title, subject description, a date of production, artistic information, music compilations, and any other types of descriptive information about a particular media asset. Further, metadata can characterize a genre that describes a media asset, such as video content, as being an advertisement, a movie, a comedy show, a sporting event, a news program, a sitcom, a talk show, an action/adventure program, or as any number of other category descriptions.

In this example system 100, the mobile network operator 102 includes a proxy service 130 that can be implemented as computer-executable instructions, such as a software application, and executed by one or more processors to implement the various embodiments described herein. Alternatively or in addition, the proxy service may be implemented as an independent service separate from the mobile network operator. In embodiments, the proxy service is implemented to manage the television content distribution to the various client devices 104.

The proxy service 130 at the mobile network operator 102 receives requests for television content from one or more of the client devices 104. The proxy service can then initiate the mobile network operator to communicate one of the requests from the client devices (as opposed to all of the requests) to the content service 106 that provides the television content (e.g., the media assets 126) to the mobile network operator for distribution to the client devices. In an implementation, the first client device that requests the television content, such as a television program or movie, initiates content data being distributed downstream from the content service, via the mobile network operator, to a proxy cache at a wireless distribution point.

The example system 100 includes wireless distribution points 132 of the mobile network operator 102 via which the requested television content can be wirelessly communicated to the client devices 104. Proxy caches are located at the wireless distribution points, such as proxy cache 134 located at the wireless distribution point 136. The proxy cache may be implemented as an HTTP proxy cache that caches content data 138 of the requested television content when received via the Internet. The mobile network operator 102 can receive the content data of the requested television content from the content service 106 via the Internet (e.g., via the communication network 108). The content data can be received as video fragments of the television content that are packetized for smooth streaming at the content service.

The proxy caches at the wireless distribution points 132 cache the content data 138 of the television content prior to the cached content data being wirelessly communicated to the client devices 104. In embodiments, the content data is cached at a proxy cache that is located at a wireless distribution point that has a wireless communication link with a client device that requested the television content. The wireless distribution points of the mobile network operator communicate the cached content data of the television content from the proxy caches to the client devices. In this manner, a wireless distribution point can emulate television multicast when the cached content data of the television content is communicated from a proxy cache to multiple client devices.

Similar to the proxy cache 134 located at the wireless distribution point 136, a server device 140 can be located at a wireless distribution point 142 of the mobile network operator 102. The server device includes a proxy cache 144 to cache content data of the requested television content, such as described with reference to the proxy cache 134. In embodiments, the server device may optionally include a proxy service 146, such as described with reference to the proxy service 130 at the mobile network operator. The proxy service 146 can receive requests for television content from one or more of the client devices 104, and then communicate one of the requests to the content service 106 that provides the television content as content data for distribution to the client devices. The proxy cache 144 caches the content data of the television content at the wireless distribution point 142 prior to the cached content data of the television content being wirelessly communicated to the client devices.

In embodiments, the mobile network operator 102 and/or the server device 140 first receives a request for the television content from one or more of the client devices 104, and then caches the content data of the requested television content. Alternatively, content data for additional television content can be received from the content service 106 before a request for the additional television content is received from a client device. The proxy caches 134, 144 can then cache the content data prior to the additional television content being requested and wirelessly communicated to the client devices.

In this example system 100, the content service 106 also includes an advertisement distribution service 148 that can be implemented as computer-executable instructions, such as a software application, and executed by one or more processors to implement the various embodiments described herein. Alternatively or in addition, the advertisement distribution service 148 may be implemented as an independent service separate from the content service. In embodiments, the advertisement distribution service is implemented to manage the distribution of advertisements 150 along with the television content to the various client devices 104. The advertisements may be targeted local advertisements that correspond to the current location of a particular client device and/or the advertisements are targeted local advertisements that correspond to an advertising locale, which includes the current location of the client device.

FIG. 2 illustrates an example system 200 in which various embodiments of current device location advertisement distribution can be implemented. The example system 200 includes the mobile network operator 102, communication network 108, and examples of wireless distribution points as described with reference to FIG. 1. As described above, the mobile network operator can receive television content (e.g., the media assets 126) from the content service 106, along with national and/or local advertisements 150. Local advertisements are generally directed to client devices that receive television content within a designated region or geographic area, and are intended to reach potential consumers of goods and services within the designated local region or geographic area, referred to herein as an advertising locale.

The mobile network operator 102 can then communicate the television content along with the advertisements to a client device via a wireless distribution point. For example, a client device 202 is located in a geographic region 204 that is covered for wireless communication with the mobile network operator by at least the wireless distribution point 206. The geographic region that is associated with the client device may be based on a service contract with a user of the client device, or a billing zip code associated with the user of the client device. However, if the client device is moved at 208 from one advertising locale to another, such as from the geographic region 204 to a different advertising locale 210, the local advertisements that correspond to the geographic region associated with the client device are likely not useful to a user of the device in the different advertising locale. For example, a business person may travel from his or her home city to a city in another state. While viewing television content on the client device 202, targeted local advertisements can be received that correspond to the current location and/or advertising locale of the client device, rather than advertisements that are local to the person's home city.

In the example system 200, the client device 202 has a current location within advertising locale 210, which is covered for wireless communication with the mobile network operator 102 by at least the wireless distribution point 212. As described with reference to FIG. 1, a proxy cache 214 is located at the wireless distribution point to cache the content data 216 of the television content prior to the cached content data being wirelessly communicated to the client device 202. In this example, the proxy cache can also cache advertisement data 218 of the advertisements that correspond to the advertising locale 210 for distribution to the client device along with the television content.

The mobile network operator 102 includes a device location service 220 that can be implemented as computer-executable instructions, such as a software application, and executed by one or more processors to implement the various embodiments described herein. Alternatively or in addition, the device location service may be implemented as an independent service separate from the mobile network operator. In embodiments, the device location service is implemented to determine that a current location of the client device 202 is not within the geographic region 204 that is associated with the client device. The device location service can then also determine the advertising locale 210 that includes the current location of the client device, and/or update the advertising locales as the client device is moved from one region to another.

The device location service 220 at the mobile network operator 102 can determine the current location of the client device 202 from location data 222 that identifies the current location of the device. The location data can include GPS location data 224 and/or regional position data 226 that correlates to the current location of the client device. The regional position data can indicate the current location of the client device based on communications via cellular towers (e.g., the wireless distribution points) or other network communication equipment that has a known location relative to an approximate location of the device. The location of a mobile phone or portable computer, for example, can be monitored for a change in location, such as from one advertising locale to another.

FIG. 3 illustrates an example system 300 that includes a example client device 104 as described with reference to FIG. 1. The example system 300 enables ubiquitous environments for a seamless user experience when using any type of computer, television, and/or mobile device. Services and applications run substantially similar in all environments for a common user experience when transitioning from one device to the next while utilizing an application, playing a video game, watching a video and television content, listening to music, and so on.

In the example system 300, multiple devices can be interconnected through a central computing device or system, which may be local to the multiple devices or may be located remotely from the multiple devices. In one embodiment, the central computing device may be a cloud of one or more server computers that are connected to the multiple devices through a network, the Internet, or other data communication link. In embodiments, this interconnection architecture enables functionality across multiple devices to provide a common and seamless experience to a user of the multiple devices. Each of the devices may have different physical configurations and capabilities, and the central computing device uses a platform to enable delivery of an experience that is both tailored to a particular device and yet common to all of the devices. In embodiments, a class of target devices is created and user experiences are tailored to the generic class of devices. A class of devices may be defined by physical features, types of usage, or other common characteristics of the devices.

In various implementations, the client device 104 may be implemented in a variety of different configurations, such as for computer 302, mobile 304, and television 306 uses. Each of these configurations includes devices that may have generally different constructs and capabilities, and the client device may be configured according to one or more of the different device classes. For example, the client device may be implemented as any type of a personal computer, desktop computer, a multi-screen computer, laptop computer, tablet, netbook, and so on.

The client device 104 may also be implemented as any type of mobile device, such as a mobile phone, portable music player, portable gaming device, a tablet computer, a multi-screen computer, and so on. The client device may also be implemented as any type of television device having or connected to generally larger display screens in casual viewing environments. These devices include televisions, set-top boxes, gaming consoles, and so on. The techniques described herein may be supported by these various configurations of the client device and are not limited to the specific examples of the embodiments described herein.

The cloud 308 includes and/or is representative of a platform 310 for network access services 312. The platform abstracts underlying functionality of hardware, such as server devices, and/or software resources of the cloud. The network access services may include applications and/or data that can be utilized while computer processing is executed on servers that are remote from the client device. For example, the network access services may include the content service 106, the proxy service 130, the advertisement distribution service 148, and/or the device location service 220 as described with reference to FIGS. 1 and 2. The network access services 312 can be provided as a service over the Internet and/or through a subscriber network, such as a cellular or WiFi network.

Example methods 400, 500, and 600 are described with reference to respective FIGS. 4, 5, and 6 in accordance with one or more embodiments of wireless distribution system proxy caches and current device location advertisement distribution. Generally, any of the functions, methods, procedures, components, and modules described herein can be implemented using software, firmware, hardware (e.g., fixed logic circuitry), manual processing, or any combination thereof. A software implementation represents program code that performs specified tasks when executed by a computer processor. The example methods may be described in the general context of computer-executable instructions, which can include software, applications, routines, programs, objects, components, data structures, procedures, modules, functions, and the like. The program code can be stored in one or more computer-readable memory devices, both local and/or remote to a computer processor. The methods may also be practiced in a distributed computing environment by multiple computer devices. Further, the features described herein are platform-independent and can be implemented on a variety of computing platforms having a variety of processors.

FIG. 4 illustrates example method(s) 400 of wireless distribution system proxy caches. The order in which the method blocks are described are not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement a method, or an alternate method.

At block 402, requests for television content are received from one or more client devices at a mobile network operator. For example, the proxy service 130 (FIG. 1) at the mobile network operator 102 receives requests for television content from one or more of the client devices 104. Alternatively or in addition, the server device 140 at the wireless distribution point 142 includes the proxy service 146 that receives requests for the television content from one or more of the client devices.

At block 404, one of the requests is communicated to a content service that provides the television content to the mobile network operator for distribution to the client devices. For example, the proxy service 130 initiates the mobile network operator 102 to communicate one of the requests from the client devices (as opposed to all of the requests) to the content service 106 that provides the television content (e.g., the media assets 126) to the mobile network operator for distribution to the client devices.

At block 406, the television content is received via the Internet from the content service as video fragments of the television content. For example, the mobile network operator 102 receives content data 138 of the television content as video fragments from the content service 106 via the Internet (e.g., via the communication network 108). The video fragments of the television content can be packetized for smooth streaming at the content service.

At block 408, content data of the television content is cached at one or more wireless distribution points of the mobile network operator. For example, the proxy cache 134 at the wireless distribution point 136 caches the content data 138 of the television content prior to the cached content data being wirelessly communicated to the client devices 104. In embodiments, the content data of the television content is cached with HTTP proxy caches when the content data is received via the Internet. Additionally, the content data is cached at a proxy cache that is located at a wireless distribution point that has a wireless communication link with a client device that requested the television content.

At block 410, the cached content data of the television content is communicated to the client devices via wireless communication from the wireless distribution points. For example, the wireless distribution point 136 of the mobile network operator 102 communicates the cached content data 138 of the television content from the proxy cache 134 to the client devices 104. In this manner, the wireless distribution point emulates television multicast when the cached content data of the television content is communicated from the proxy cache to multiple client devices.

At block 412, additional content data for additional television content is received before a request for the additional television content is received from a client device. At block 414, the additional content data is cached at the one or more wireless distribution points of the mobile network operator. For example, the mobile network operator 102 receives content data for additional television content from the content service 106 before a request for the additional television content is received from a client device. The proxy caches 134, 144 can then cache the content data prior to the additional television content being requested and wirelessly communicated to the client devices.

FIG. 5 illustrates example method(s) 500 of current device location advertisement distribution, and is described with reference to a mobile network operator. The order in which the method blocks are described are not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement a method, or an alternate method.

At block 502, television content and advertisements are received from a content service for distribution to a client device via a wireless distribution point. For example, the mobile network operator 102 (FIG. 1) receives television content (e.g., the media assets 126) from the content service 106, along with national and/or local advertisements 150. The television content can include local advertisements that correspond to a geographic region associated with the client device.

At block 504, location data is received that identifies a current location of the client device. For example, the device location service 220 (FIG. 2) at the mobile network operator 102 receives the location data 222 from the client device 202, and the location data identifies the current location of the device. The location data can include GPS location data 224 and/or regional position data 226 that correlates to the current location of the client device. The regional position data can indicate the current location of the client device based on communications via cellular towers (e.g., the wireless distribution points) or other network communication equipment that has a known location relative to an approximate location of the device.

At block 506, a determination is made as to whether the client device is located within a geographic region that is associated with the device. For example, the client device 202 may be located within the geographic region 204 that is associated with the device. The geographic region that is associated with the client device may be based on a service contract with a user of the client device, and/or a billing zip code associated with the user of the client device. If the current location of the client device is not within the geographic region that is associated with the client device (i.e., “no” from block 506), then at block 508, an advertising locale that includes the current location of the client device is determined. For example, the device location service 220 determines that the current location of the client device 202 is within the advertising locale 210.

If the current location of the client device is within the geographic region (also an advertising locale) that is associated with the client device (i.e., “yes” from block 506), or continuing from block 508, then at block 510, the television content is updated with advertisements that correspond to the advertising locale, which includes the current location of the client device. For example, the television content is updated with targeted local advertisements that correspond to the current location and/or the advertising locale of the client device.

At block 512, the television content along with the advertisements is communicated to the client device at the current location of the client device. For example, the wireless distribution point 212 of the mobile network operator 102 communicates the television content (e.g., the cached content data 216) along with targeted local advertisements (e.g., the advertisement data 218) to the client device at the current location within the advertising locale 210. At block 514, the advertising locale for the client device is updated as the client device is moved from one region to another. For example, the device location service 220 updates the advertising locales as the client device is moved from one region to another.

FIG. 6 illustrates example method(s) 600 of current device location advertisement distribution, and is described with reference to a content service. The order in which the method blocks are described are not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement a method, or an alternate method.

At block 602, a request for television content is received from a mobile network operator that communicates the television content to a client device via a wireless distribution point. For example, the content service 106 (FIG. 1) receives a request for television content (e.g., media assets 126) from the mobile network operator 102 that then communicates the television content to a client device 104 via a wireless distribution point 132. At block 604, location data is received that identifies a current location of the client device. For example, the content service 106 receives the location data 222 (FIG. 2) from the client device, and the location data identifies the current location of the device. The location data can include GPS location data 224 and/or regional position data 226 that correlates to the current location of the client device.

At block 606, an advertising locale is determined that includes the current location of the client device. For example, the advertisement distribution service 148 at the content service 106 determines that the current location of the client device 202 is within the advertising locale 210. At block 608, the television content is updated to include advertisements that correspond to the advertising locale. For example, the advertisement distribution service 148 at the content service 106 updates television content to include targeted local advertisements that correspond to the current location and/or advertising locale of the client device.

At block 610, the television content is distributed to the mobile network operator for communication to the client device along with the advertisements that correspond to the advertising locale. For example, the content service 106 distributes the television content (e.g., media assets 126) along with the advertisements 150 to the mobile network operator 102 for wireless communication to the client device. At block 612, the advertising locale for the client device is updated as the client device is moved from one region to another. For example, the advertisement distribution service 148 continues to receive location data that identifies a current location of the client device (e.g., at block 604), and updates the advertising locale that includes the current location of the client device (e.g., at block 606).

FIG. 7 illustrates various components of an example device 700 that can be implemented as any of the devices, or services implemented by devices, described with reference to the previous FIGS. 1-6. In embodiments, the device may be implemented as any one or combination of a fixed or mobile device, in any form of a consumer, computer, server, portable, user, communication, phone, navigation, television, appliance, gaming, media playback, and/or electronic device. The device may also be associated with a user (i.e., a person) and/or an entity that operates the device such that a device describes logical devices that include users, software, firmware, hardware, and/or a combination of devices.

The device 700 includes communication devices 702 that enable wired and/or wireless communication of device data 704, such as received data, data that is being received, data scheduled for broadcast, data packets of the data, etc. The device data or other device content can include configuration settings of the device, media content stored on the device, and/or information associated with a user of the device. Media content stored on the device can include any type of audio, video, and/or image data. The device includes one or more data inputs 706 via which any type of data, media content, and/or inputs can be received, such as user-selectable inputs, messages, communications, music, television content, recorded video content, and any other type of audio, video, and/or image data received from any content and/or data source.
